Specification of Letters Patent.

Patented Jan. 16,1912.

Application led January 14, 1910. Serial No. 538,006.

y coal or fuel, provision being made to supply the latter withcombustible vapor above and below the bed of fuel, so'as Vto cause moreperfect combustion and a high degree of heat; provision being made alsofor combining air and steam and directing the same to the fire as apowerful draft of comb-ustible vapor, and furthermore of means forutilizing the products of combustion in the smoke flue, heating said airand steam, andy for heating the water from which said steam is producedprior to admission into the generator.

For the purpose of explaining the invention, the accompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be Varied, and so it is to beunderstood that the invention is not limited to the specific arrangementand organization shown and described.

Figure 1 represents a perspective view of a furnace embodying myinvention. Fig. 2 represents a vertical section thereof. Fig. 3represents a horizontal section on line m-m Fig. 2.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings 1 designates the casing of a furnace, 2 theash pit thereof, and 8 the grate bars thereof, the latter beingpivotally mounted on the casing 1, and connected with and coupled by thestringers 4, which are provided vwith the lever 5, whereby the saidstringers and consequently the grate bars may be operated for rakingpurposes, said lever being mounted at 6 on the exterior of the casing 1,and thus convenient of access.

Interposed between the bars 3 and supports on the wall of the casing,are pipes 7, having jets 8 on the upper side thereof, said pipes havingconnected with them the tubes 9 which extend through the side of thecasing and communicate by means of the being secured to the exterior ofthe casing and adapted to contain hydrocarbon or other fluid which is tobe vaporized being injectedfagainst the fuel on the grate bars andburned therewith, thus intensifying the resultant heat, said pipes 7being heated by the fire and hot air injected into the ash pit, as willbe hereinafter more fully described.

The furnace has doors 13 above the grate bars for usual purposes; andthe plate 14 for closing the ash pit air tight, the same being held inposition by the yoke 15, which is pivotally connected with the casing 1,and the screw 16 which is fitted to the front ofsaid yoke and adapted totighten against said plate. When the screw 16 is loosened,

the yoke 15 may be made to allowT the plate 14: to be withdrawn, thusuncovering the openings of the ash pit and permitting access to theinterior of the latter.

In the combustion chamber 17 are the pipes 18, which are supported onthe wall of the casing, the same having jets 19 on the upper sidethereof, said pipes having connected with them the tubes 20 which extendthrough the side of the casing and compipes 10 and 11, with the tank 12,the latter municate by means of the pipes 21 and 22 with the tank 23,the latter being secured to the exterior of the casing and adapted tocontain fluid or material whichmay be converted into a combustible vaporin the pipes 18 and injected by the jets 19 into the chamber 17, whereit is consumed with the products ofv combustion, thus furtherintensifying the heat of the furnace.

24 designates the smoke iue the same extending from the top of thecasing and having an elbow which opens to the atmosphere, one limb ofthe elbow containing the coil 25 shown in dotted lines Fig. 1, one endof said coil having connected with it the air supply pipe 26, and theot-her end having connected with it the air conveyer pipe 27, the latterextending to the blower or blast apparatus 28, which opens as at 29 intothe ash pit 2.

A pipe 30 is connected with a source of steam, in the present case, theboiler or generator 31 and is connected with the air pipe 26 and wherebysteam and air are directed into the coil 25, and as the latter iscontained in the smoke flue 21 which is heated by the produ cts ofcombustion, the steam is nace with a powerful draft and a vaporil whichis directed to the fuel, to assistthe combustion 'thereof to a highdegree while also highly heating the pipes 7 for Vaporiz-A ing thehydrocarbon fluid therein. Y

In the smoke flue 24 is acoil 82 with one end of which is connected thepipe 33 for directing Water into the steam generator,` the other end ofsaid coil having connected with it the pipe 34 which -passes throughsaid iue and the adjacent wall of the casing into the generator, itbeing noticed that the products of combustion in said fiue 24 areutilized to heat the coil 32 and adjacent portion of the pipe 34 thusheating the feed water of the generator before entrance into the latter.

Having thus described my invention',

what I claimy as new and desire to secure by Letters Patent, is

A furnaceV having. grate bars, a tightly closed ash pit,`1neans forsupplying a blast of air and steam .below said grate bars, means forheating said' air prior to its entrance to said blast-supplying means,oil

ingtubes.
